“Nothing great was ever achieved without enthusiasm.”

“At moments of great enthusiasm it seems to me that no one in the world has ever made something this beautiful and important.”

“Without inspiration, which fills the soul with a healthy warmth, nothing great can ever be brought to pass.”

“History sometimes reproduces, at a distance of many years, the same combinations of circumstances that generate great achievements. But nothing ever repeats itself in exactly the same way.”

“Never was anything great achieved without danger.”

“Nothing is as contagious as enthusiasm. It is the real allegory of the myth of Orpheus; it moves stones, and charms brutes. It is the genius of sincerity, and truth accomplishes no victories without it.”

“Optimism is the faith that leads to achievement; nothing can be done without hope.”

“Oh, but you know, you do not achieve anything without trouble, ever.”

“Nothing worthwhile is ever without complications.”

“Nothing is better than a justified enthusiasm.”
